HHHHmmmnnn.....I Ching.....you really shouldn't scratch or it will get worse.

Seriously, from Astronuc's web pages, definitely check out the Tao Te Ching by Lao Tsu. Its a rather small volume that easily fits in your back pocket, but its full of great verse and serious thought. Sun Tsu's Art of War is another classic, less on religious practice and more on approaches to life obstacles, business, etc. Many business schools have this as suggested reading. If you get further into martial arts philosophy, check out Miyamoto Musashi's Book of Five Rings, a classic on swordsmanship and combat philosophy. More recent texts like Zen in the Martial Arts and Living the Martial Way are also good reads.

I started using the I ching years ago, and then learned Tarot. I ended up throwing away my tarot cards...but my roommate bacame interested in them lately. So instead I'm teaching her about the I ching. I'ts really a better system I think than tarot but I might be wrong. You have to try some to know which you prefer. But the drawback to that is it's less time getting really good with one system which is what REALLY pays off. It's not a game though, it's definitely an oracle.
